CHURN.

SPECIFICATION forming part of Letters Patent No. 534,889, dated February 26,1 895.

Application filed March 5,1894. Serial No. 502,407. (No model.)

To all whom it may concern.-

Be it known that we, MICHAEL FRANCIS KELLY and NILs AARON HAGQUIST, of Blossburg, in the county of Tioga and State of Pennsylvania, have invented a new and useful Improvement in Ohurns, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in churns, and it has for its object to produce a churn in which there will be two independent dashers, one capable of a rotary movement and the other of a vertical movement, and furthermore, to so construct the churn that either dasher may be used independent of the other.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the Views.

Figure 1 is a vertical section through the churn, the said section being taken practically on the line 1-1 of Fig. 2. Fig. 2 is a plan View thereof. Fig. 3 is a cross section taken essentially on the line 3-3 of Fig. 1. Fig. 4 is a detail View illustrating the manner in which the churn body is mounted upon its standards; and Fig. 5 is a detail view illustrating the manner in which the reciprocatin g dasher-is connected with the driving mechanism.

In carrying out the invention the frame of the machine consists of a base A, from which standards B, are projected upward one at each side, and each standard B is provided with an angular slot 10 in one of its sides, adapted to receive pins 11 and fulcrum the same, the said pins being attached to opposite sides of the churn body 0, and the pins are usually located at or about the central portion of the body.

In the upper end of the standards a shaft 12 is journaled in suitable bearings, provided with a crank arm 13 at one point in its length, and the shaft is further provided with abeveled gear 14 which is adjustably secured thereon. The top of the churn body is covered by a lid 0'. This lid is made in two sections 15 and 16, and said sections are flanged to fit over the upper edge of the body and cutout to receive the standards 13. Each section of the cover beneath the crank arm in the shaft 12 is provided with a slot 17, the two slots being in registry, as shown in Figs. 1 and 2. The shaft at one end is provided with a pulley 18, which is connected with a wheel 19, held to turn upon a suitabie axle supported by one of the standards, the said connection being through the medium of a belt 20. The wheel 19 may be turned by hand if desired, but it will be understood that the shaft may be revolved by any applied power.

The body of the churn carries two dashers D and D. The dasher D is adapted to have rotary movement, and consists of a hub 21 and plates 22 introduced in the sides of the hub or attached thereto. These plates may be in any desired number and extend diagonally with reference to the axis of the hub, and are preferably made somewhat diamondshaped in cross section, and usually their lower edges near the hub are upwardly curved or recessed to permit agitation of the milk at the extreme bottom portion of the churn body.

The hub of the rotary dasher is secured upon ashaft 23, which shaft is carried upward through a suitable openingin the cover of the churn and beyond the said cover, being provided at its upper end with a beveled gear 25, the said gear being adapted to mesh with the adjustable gear 14 on the driving shaft. The upper dasher D, is adapted to have vertical reciprocating movement, and consists of a sleeve 27, held to slide upon the shaft 23, and two disk plates 28, located one preferably at the bottom of the sleeve and the other near the top, the said disk plates being provided with suitable apertures 29 in them.

The lower portion of the vertically reciprocating dasher usually rests upon the top of the rotary dasher, and motion is imparted to the vertically reciprocating dasher through the medium of an arm 30, attached in any approved manner to the upper portion of the sleeve 27. This arm is carried upward through the slot 17 in the cover, and is made to terminate at its upper end in a hook or open eye 31, which partially encircles the crank of the drive shaft. Abolt 32 is carried by this arm 30, and the said bolt carries a shorter arm 33, provided at its upper end with a segmental head 34:, and with a crank arm 35 at its lower end. This crank 35, is pivotally attached to the main arm 30 below the bolt 32, and when the segmental head of the auxiliary arm 33, which maybe properly termed a locking bar, is brought up to an engagement with the crank of the drive shaft, it will prevent the arm 30 from being withdrawn from said crank, and'the locking bar is held in its locked position through the medium of a nut 36, located on the bolt 32. The sections of the cover maybe held together in any approved manner. Usually hooks 16" are employed for the purpose, engaging with studs upon the opposing section.

The locking bar 33, extends above the top of the churn, and when this locking bar is closed against the crank arm of the drive shaft and the shaft is revolved, the rotary dasher will be given a rotary movement, and the upper dasher a vertically reciprocating movement, the two operating simultaneously. If, however, the rotary dasher only is needed, the locking bar 33, may be disengaged from the drive shaft, and the arm 30 likewise disengaged, without removing the cover of the 'churn, and the upper dasher will then remain inactive. If the upper dasheris required, and the rotary or lower dash is to remain idle, this is accomplished by shifting the gear 14 A churn constructed as above set forth is exceedingly simple, durable and economical, and has the advantage of two dashers having different movements and capable of use combinedly, or one independent of the other.

Having thus described our invention, we claim as new and desire to secure by Letters Patent In a churn, the combination with a churn body, a drive shaft above the body and provided with a pinion and a crank arm, a shaft in the churn body and provided with a pinion on its upper end meshing with the pinion of the drive shaft, a dasher on the lower end of the said shaft, and a second dasher fitted to slide on the shaft of a bar having its lower end secured to the second dasher and provided with an open eye partly encircling the crank of the drive shaft, a second arm pivoted to the first named arm and having a segmental head, and a bolt for clamping the eye and head of the arms on the crank shaft, substantially as herein shown and described.
